.and useful Improvements in Vulcanizing Apparatus, of-which the following is a full, clear, and eXact description.

My invention relates to vulcanizing' apparatus and more particularlyto a type thereof wherein the articles being vulcanized aresubjected to. the action of a controllable that it permits the treatment of all articles in the chamber at any time under substantially the same conditions and results in greater uniformity in the quality of the goods vulcanized at the same time.v The invention has particular adaptability to that type of apparatus including a plurality of cars having a tubular, frame upon which hollow forms supporting the articles are detachably mounted. The forms are in communication with said frame preferably by means of nipples and said car frames are in communication with pressure controlling apparatus for creating and maintaining a dliferential of pressure upon opposlte sides of the articles upon the forms. By means of my invention each of the carsis, placed 1n communication with the pressure controlling apparatus by means of a pipe system having a plurality of openings communicating with said car frames respectively, said openings being'so arranged that the eifective pressure or suction, as the case may be, at each of these points, will be substantially the same as at every other.

The invention consists primarily in a vulcanizing apparatus embodying therein a vulcanizing chamber, a pressure controlling apparatus, and a pipe system lead ng from said pressure controlling apparatus and having a plurality of openings so arranged so that each will be at the same distance from said pressure controlling apparatus and leading into said chamber at widely separated points; and in such other, novel features of construction and combination of parts as are hereinafter set forth and described and more particularly pointed out in the'claims hereto appended.

Referring to the drawings Figure 1 is a horizontal section of an apparatus embodymg my invention, and Fig. 2 is a vertical section thereof.

Like letters refer to like parts in both of said views.

In the accompanying drawings I have shown an embodiment of the invention wherein a plurality of cars having tubular frames are used, and the vulcanizing medium is introduced to the chamber about the articles on said cars. The I vulcanizing chamber 1, is of the usual, or any desired,

construction, andthe walls thereof may be jacketed or otherwise equipped to minimize heat radiation or assist in raising the temperature within the chamber to, or maintaining it at, the vulcanizing point. This chamher is provided with the usual tracks 2 and closure 3. In connection with said chamher 1, I provide any desired form of pressure controlling apparatus shown conventionally at ,4, as a suction pump. Communicating with the said apparatus 4 is a pipe system including the main pipe line 5. The wall of the chamber I has an opening there through at 6 and saidpipe line 5 passes through said opening and into said chamber, suitable packing being provided about said pipe and said opening 6. When theapparatus shown is in use, a plurality of cars 7 are run upon the tracks 2 into thecliamber 1. Eachof these'cars has a tubular frame 8, the barsof whichare provided with a plurality of hollow nipples 9 communicating witlr frame.

the interior of said Mounted upon and communicatingv Z. wlth each of said nipples is a hollow form,

10 PPorting the article to be vulcanized.

' These forms 10 are provided with fluid ,ducts Q.

as 10 to permit the'withdrawal offiui ds' the article through said form. The pipe system is provided with a plurality of openings communicating with the main pipe line 5 and corresponding in num izing chamber, such as will result from the employment of a slngle plpe connection hav ing extensions or branches provided with openings, all at the same conduit dlstance from the pressure-controlhng apparatus, the

effective suction or pressure will be equal at all of said openings. Hence by arranging these openings at widely separated points in the vulcanizing chamber, an equal suction or pressure will be simultaneously set up at all of the openings and fluids will be withdrawn from or delivered to different parts of the vulcanizing chamber in substantially the same amounts. This insures substantial uniformity in the pressure conditions throughout all parts of the said chamber. This system of piping is particularly adapted for use in connection with cars, as herein shown and described.

In the drawings pipe extensions or branches are shown at 11 and 12, each of said extensions or branches being provided with end fittings 13 and 14:, 15 and 16 at opposite ends thereof respectively. Communicating with each of the branch pipes 11 and 12 at a point equidistant from each end fitting, is a pipe section'17 having a T- fitting 18 centrally of the length thereof. The mainpipe line 5 is connected with said T-fitting. The end fittings may be provided with the usual form of couplings as shown, thereby providing ready means for connecting and disconnecting the cars and the piping system.

From the foregoing description it will be observed that the conduit distance between each end fitting and the pressure-controlling or suction apparatus is the same and that therefore the effective suction or pressure at each opening and the rate of flow of the fluid entering and passing through each branch pipe will be the same, and substantially uniform pressure conditions within each car 7 will be maintained.

Vhile I- have shown four end fittings, it

is apparent that the number may be varied according to the dimensions of the vulcanizing chamber. Furthermore, any opening may be closed without modifying the operative effect as to the remaining intake fittings.

It is essential that the length of the piping between each end fitting and the main pipe line, or the pressure-reducing or suction apparatus shall be the same, and any arrangement by which this condition may be established will accomplish the purpose of my invention.

While I have described my apparatus in connection with the creation ofa vacuum or leading from said pressure controlling apparatus and having a plurality of openings so arranged as to be at the same conduit distance from said pressure controlling apparatus, and leading-into said chamber.
